Answer:

The correct option is D) 11.4

Step-by-step explanation:

Given points are A(5,7) and B(-2,-2)

The distance between two points is given by

L= $\sqrt{(X2-X1)^{2}+{(Y2-Y1)^{2}}$

To find the distance between A(5,7) and B(-2,-2)

L= $\sqrt{(X2-X1)^{2}+{(Y2-Y1)^{2}}$

L= $\sqrt{((-2)-5)^{2}+{((-2)-7)^{2}}$

L= $\sqrt{(-7)^{2}+{(-9)^{2}}$

L= $\sqrt{49+81}$

L=11.4

Thus,

The correct option is D) 11.4

Area of a Circle

Cloud [144]

Answer:

The diameter of the pond is 38 m.

The radius of the pond is 19 m.

The area of the pond is 361 m^2.

Step-by-step explanation:

We know that the circumference C of a circle is equal to

$C=\pi D$

In this case, C is equal to 120 m.

The diameter is then:

$D=C/\pi=120/3.14=38.21\approx 38$

Rounded to the nearest whole number, the diameter is D=38 metres.

The radius is equal to half the diameter, so the radius of this pond is R=19 metres.

$R=D/2=38/2=19$

The area can be calculated from the radius as:

$A=r^2=19^2=361$

The area is 361 m^2

trasher [3.6K]

Answer:

$z=5\left(\cos \left(\dfrac{3\pi}{2}\right)+i\sin \left(\dfrac{3\pi}{2}\right)\right)$

Step-by-step explanation:

If a complex number is z=a+ib, then the trigonometric form of complex number is

$z=r(\cos \theta +i\sin \theta)$

where, $r=\sqrt{a^2+b^2}$ and $\tan \theta=\dfrac{b}{a}$ , $\theta$ is called the argument of z, $0\leq \theta\leq 2\pi$ .

The given complex number is -5i.

It can be rewritten as

$z=0-5i$

Here, a=0 and b=-5. $\theta$ lies in 4th quadrant.

$r=\sqrt{0^2+(-5)^2}=5$

$\tan \theta=\dfrac{-5}{0}$

$\tan \theta=\infty$

$\theta=2\pi -\dfrac{\pi}{2}$ $[\because \text{In 4th quadrant }\theta=2\pi-\theta]$

$\theta=\dfrac{3\pi}{2}$

So, the trigonometric form is

$z=5\left(\cos \left(\dfrac{3\pi}{2}\right)+i\sin \left(\dfrac{3\pi}{2}\right)\right)$
